1The io-streams library contains simple and easy to use primitives for I/O 2using streams. Based on simple types with one type parameter (`InputStream a` 3and `OutputStream a`), io-streams provides a basic interface to 4side-effecting input and output in `IO` monad with the following 5features: 6 7 * three fundamental I/O primitives that anyone can understand: `read :: 8 InputStream a -> IO (Maybe a)`, `unRead :: a -> InputStream a -> IO ()`, 9 and `write :: Maybe a -> OutputStream a -> IO ()`. 10 11 * simple types and side-effecting IO operations mean straightforward and 12 simple exception handling and resource cleanup using standard Haskell 13 facilities like `bracket`. 14 15 * code to transform files, handles, and sockets to streams 16 17 * a variety of combinators for wrapping and transforming streams, including 18 compression and decompression using zlib, controlling precisely how many 19 bytes are read to or written from a socket, buffering output using 20 `blaze-builder`, etc. 21 22 * support for parsing from streams using `attoparsec`. 23
